Looking at this shot of our rig I think it's fairly obvious I need to raise my hitch. The B&W Companion is set in the middle of both it's vertical and fore-and-aft positions. I can take the hitch up, but I'm not sure that will be enough?

Can the pin box be adjusted for height? I can raise the B&W myself but I don't have a clue about the pin box, and after years of experience I have come to avoid messing with things I am unfamiliar with.
